kasetto - declarative AI agent environment manager, written in Rust

The Problem The more AI coding tools we adopted, the messier our setup got. Skills and MCP servers installed manually, via individual commands, or copy-pasted from docs. Scattered across Claude Code, Cursor, Codex, Windsurf - with no way to version any of it, no way to share it with teammates, no way to reproduce it on a new machine or project. Every new team member meant walking them through the same manual steps. Every new machine meant doing it all over again. And if someone changed a skill or added an MCP server, there was no way to propagate that to the rest of the team. Sound familiar? The Idea I built kasetto to fix that. The idea is borrowed from things I already loved - the declarative reproducibility of dotfiles, the simplicity of uv for Python packages. What uv did
